ABOUT THE DIFFERENCE

Silica Aerogel Insulation Blanket are the least dense solid in the world today. Pyrogel Aerogel insulation blanket have low thermal conductivity, high temperature resistance, flame retardancy, low density, and also have certain waterproof effect.

Silica aerogel insulation blanket is the best thermal insulation blanket material so far, its pore size is lower than the atmospheric pressure under normal pressure, so the air molecules in aerogel gap are in a static state, thus avoiding the convection heat transfer of the air. The very low volume density of the Silica Aerogel Insulation and the bending path of the nanoscale structure also prevent the gas and solid heat conduction, and the “infinitely many” void walls can minimize the thermal radiation. Together, these three functions almost blocked all the ways of heat transfer, which is the adiabatic effect of aerogels to other materials.

1st advantage is Excellent heat insulation effect

The heat insulation effect of Silica Aerogel Insulation Felt is 2-5 times that of traditional insulation material, and the theoretical lifetime measured by Arrhenius experiment is 20 years. It’s almost the same life as the building.

2, reduce the thickness of insulation layer

The aerogel felt has the same thermal insulation effect and the thickness is only a fraction of the traditional material. After heat preservation, the heat loss is small and the utilization rate of space is high. And at high temperatures, the above performance advantages are more obvious.

3, hydrophobicity and fire resistance

Aerogel blanket water repellent, which can effectively prevent moisture from entering pipes and equipment. At the same time, it has the fireproof performance of the building A1, and the three-dimensional network structure of the aerogel avoids the heat insulation effect of other thermal insulation materials in the long-term high temperature use, such as sinter deformation, settlement and so on.

4. Convenient construction

The aerogel blanket is light, easy to cut and sewn to adapt to various forms of pipes and equipment for thermal insulation, and the installation time and manpower are less.

5, save transportation cost

Aerogels can be used in an environment of -200~650 degrees Celsius, but it is usually used in aerogel insulation blanket. Based on the fiber’s fire resistance temperature, in principle we will control the temperature of 200 degrees Celsius. The hot melt adhesive used for aluminum foil or cloth and insulation blanket will not melt and ensure normal use. Of course, we keep insulation on the exterior wall. Aerogel insulation will also be done when other fixed, plate, screw and so on will be used.

There will be other conditions in the aerogel insulation blanket in practical applications, but the effectiveness will always come in and out of the ideal, but Gallic aerogel insulation blanket for all users, designed in all aspects, such as the hydrophilic and hydrophobicity of aerogel insulation blanket, can be done.

Uses of Fiberglass Fabrics

When it comes to composite construction or boat building, many people turn to fiberglass fabrics to get the job done right. Whether used for reinforcement, coating or laminating, professionals and DIY enthusiasts all over the world are quickly recognizing the benefits of this versatile composite. If you are new to composite materials or considering using fiberglass for a project, you came to the perfect place. In this guide, we will explore the properties and uses of fiberglass fabrics to help you better understand this convenient and cost-effective material.

With so many composites to choose from, understanding what each textile is and means for your project can be difficult or even daunting. Fortunately, the composite experts are here to help. Fiberglass cloth consists of bulk, chopped fibers or continuous strands of different kinds of glass. Whether in bulk form or a continuous strand, the combined physical strength of those glass fibers exceeds the properties that each of them has individually. This fiber-reinforced composite is typically flattened into sheets or randomly arranged and woven into fabrics for use in all sorts of applications. Fiberglass fabric is lightweight, strong, and less brittle than other composite materials. One of the most prized properties of fiberglass is its ability to be molded into various complicated shapes.
